Exploratory Study on Carbon Dioxide Blends With Low‐GWP Working Fluids for Medium and High‐Temperature Heat Pumps Under Step Pressure

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Research on Optimization of Flow Field and Combustion Performance in Boilers With Combined Near‐Wall Air Supply Systems

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the

Design and Performance Analysis of a Thermal Energy Storage System With Steam Extraction and Electric Heating in a Coal‐Fired Power Plant

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To alleviate the impact of the instability of renewable energy power generation on the power grid, coal‐fired power plants (CFPPs) have to undertake peak shaving tasks, which puts forward high requirements for the flexibility of CFPPs. To enhance the flexibility of CFPPs to consume more renewable energy, this paper innovatively proposes a ...

Stability and Behavior of Bulk Nanobubbles Under Reservoir Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Compared with microbubbles, nanobubbles exhibit superior stability, higher specific surface area, and smaller size. These characteristics have increasingly attracted the attention of petroleum researchers. However, existing literature lacks studies on nanobubble concentration and size under harsh reservoir conditions. To address this gap, this

Advanced boil-off gas studies for liquefied natural gas

Applied Thermal Engineering, 2021
Abstract Current methods of estimating boil-off gas (BOG) rates for large-scale liquefied natural gas (LNG) storage tanks are largely empirical and based on limited available experimental data. More accurate models would be extremely valuable for estimating the potential for excessive BOG generation during LNG storage and transportation scenarios as ...

Application of Boil Off Gas Compressors in LNG Plants

Volume 3B: Oil and Gas Applications; Organic Rankine Cycle Power Systems; Supercritical CO2 Power Cycles; Wind Energy, 2014
This paper discusses complexities and challenges of managing boil off gas (BOG) in LNG liquefaction plants. Most publications in the past have focused on regasification terminals and have not addressed the area of liquefaction plants. The paper discusses the generation and management of BOG and the associated networks and machinery to manage it.

A voyage optimization model of LNG carriers considering boil-off gas

OCEANS 2019 MTS/IEEE SEATTLE, 2019
A voyage optimization model is proposed to minimize the operating costs of LNGC (Liquefied Natural Gas Carrier). The model is utilized to suggest the RPM and route plan of the vessel based on the amount of boil-off gas generated. Voyage optimization of LNGC is different from that of general cargo ships because of the natural characteristics of its ...
